C-Band Cylindrical Array.
Abstract
The report details the design and fabrication of a C-band (6.4-8.9 GHz) cylindrical array with 360 degree azimuth coverage and an elevation beam squinted out of the azimuth plane. The array was designed using computer program calculations to determine such parameters as allowable element spacing, allowable squint angle (without grating lobes) and element positional tolerance. The element phase and amplitude excitation errors which were acceptable were also determined by the computer program. The array arrangement sleected was eight rows of eight elements staggered and stacked in a cylindrical configuration. The element type selected was a 'fat dipole' over a cup reflector which exhibited a 42% bandwidth. The feed network was a series of microcircuit power dividers arranged with one input and 64 outputs which exhibited an octave bandwidth. (Modified author abstract)
